## Peering

You can use peer UTSA for fast connection or state sync

```shell
peers="546d284c7b7f7a717b06d17002f28ee746ded36f@144.76.29.90:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.lumen/config/config.toml
```

The address book is updated once an hour. You can use it for quick launch

```shell
wget -O $HOME/.lumen/config/addrbook.json "https://share.utsa.tech/lumen/addrbook.json"
```
